The New Patek Philippe Twenty~4 7340/1R Perpetual Calendar

Introduced in 1999, the Twenty~4 collection was Patek Philippe’s first dedicated line of feminine timepieces. The original model featured an Art Deco-inspired manchette (cuff) design, but in 2018, the brand unveiled the Twenty~4 Automatic, which is a round-cased iteration powered by an automatic movement. This year, Patek Philippe elevates the collection further by introducing a perpetual calendar complication, marking the collection's debut in the realm of Grand Complications.
Crafted entirely in 18K rose gold, the watch features a 36mm case with a slender profile of just 9.95mm, making it sit gracefully on the wrist. The case is meticulously finished with a combination of polished and brushed surfaces, enhancing its refined aesthetic. Two dial options are available. The Ref. 7340/1R-001 features a silvery opaline dial with a vertical satin finish, evoking the texture of shantung silk that feature irregular texture, while the Ref. 7340/1R-010 presents an olive green sunburst dial for a more contemporary appeal.

sandwich dial

It is a type of watch dial design distinguished by its three-dimensional layout and multi-layered construction, enhancing both aesthetics and time readability. It typically consists of two main layers: The bottom layer, often coated with luminescent material, features perforations for hour markers and numerals. The top layer, which contains the hour markers and numerals, is usually solid and opaque.

The luminescent material on the lower layer shines through the cutouts in the upper layer, creating a strong contrast that makes the watch face highly visible, especially in low-light conditions. This design was originally developed by the brand "Panerai" for its military watches to improve visibility during underwater and nighttime operations.
